* MIN MAX tests are for Fluke 12 only.
** Calibrator 50Ω divider override.
† The dc volts annunciator must be on.
†† Conducting performance tests of the 400Ω, 4 kΩ, 40 kΩ, and 1 µF ranges (tests no. 22, 23, 24,
25, 26, 31, and 32) verifies that the discrete and integrated circuitry needed to support the other
capacitance ranges are working within specifications. Therefore, these tests indirectly verify that the
meter will meet specification in the 10 µF, 100 µF, 1000 µF, and 10,000 µF ranges.
††† In the V-CHEK mode, the UUT uses a low-impedance thermistor (approx. 2.5 kΩ) for circuit
protection and load testing (referred to as lo-Z input circuitry). When using the 5100B or 5700A to drive
the UUT with higher voltages, avoid an overload/current limit condition by gradually stepping the voltage
up (waiting two seconds between each step) from 90.0V, 120.0V, 180.0V and 350.0V at 80 Hz each step.
